Questions about alternative history fiction, or stories based on histories that explore what might have happened if certain historical events and figures had been different. Also sometimes referred to as "alternate" history.
Alternate or alternative history is a genre of speculative fiction consisting of stories in which one or more historical events occur differently. These stories usually contain "what if" scenarios at crucial points in history and present outcomes other than those in the historical record. The stories are conjectural but are sometimes based on fact. Alternate history has been seen as a sub-genre of literary fiction, science fiction, or historical fiction; alternate history works may use tropes from any or all of these genres.
